  • An Inversion Framework for Optimizing Non-Methane VOC Emissions Using Remote Sensing and Airborne Observations in Northeast Asia During the KORUS-AQ Field Campaign 
    Choi, Jinkyul; Henze, Daven K.; Cao, Hansen; Nowlan, Caroline R.; González Abad, Gonzalo; Kwon, Hyeong-Ahn; Lee, Hyung-Min; Oak, Yujin J.; Park, Rokjin J.; Bates, Kelvin H.; Maasakkers, Joannes D.; Wisthaler, Armin; Weinheimer, Andrew J. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    We aim to reduce uncertainties in CH2O and other volatile organic carbon (VOC) emissions through assimilation of remote sensing data. We first update a three-dimensional (3D) chemical transport model, GEOS-Chem with the ...
  • Evaluation of Secondary Organic Aerosol (SOA) Simulations for Seoul, Korea 
    Oak, Yujin J.; Park, Rokjin J.; Jo, Duseong S.; Hodzic, Alma; Jimenez, Jose L.; Campuzano-Jost, Pedro; Nault, Benjamin A.; Kim, Hwajin; Kim, Hyeonmin; Ha, Eunjo S.; Song, Chang-Keun; Yi, Seung-Muk; Diskin, Glenn S.; Weinheimer, Andrew J.; Blake, Donald R.; Wisthaler, Armin; Shim, Mihee; Shin, Yoonmi (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Organic aerosols (OA) represent a significant fraction of total submicron particulate matter (PM1) concentrations globally, including densely populated megacities such as Seoul. However, scientific understanding of the ...
  • Evaluation of simulated O3 production efficiency during the KORUS-AQ campaign: Implications for anthropogenic NOx emissions in Korea 
    Oak, Yujin J.; Park, Rokjin J; Schroeder, Jason R.; Crawford, James H.; Blake, Donald R.; Weinheimer, Andrew J.; Woo, Jung-Hun; Kim, Sang-Woo; Yeo, Huidong; Fried, Alan; Wisthaler, Armin; Brune, William H. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    We examine O3 production and its sensitivity to precursor gases and boundary layer mixing in Korea by using a 3-D global chemistry transport model and extensive observations during the KORea-US cooperative Air Quality field ...
  • Top-down estimates of anthropogenic VOC emissions in South Korea using formaldehyde vertical column densities from aircraft during the KORUS-AQ campaign 
    Kwon, Hyeong-Ahn; Park, Rokjin; Oak, Yujin J.; Nowlan, Caroline R.; Janz, Scott; Kowalewski, Matthew G.; Fried, Alan; Walega, James; Bates, Kelvin H.; Choi, Jinkyul; Blake, Donald R.; Wisthaler, Armin; Woo, Jung-Hun (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Nonmethane volatile organic compounds (NMVOCs) result in ozone and aerosol production that adversely affects the environment and human health. For modeling purposes, anthropogenic NMVOC emissions have been typically compiled ...
